The Ragozin Defense arises from the Queen's Gambit when Black opts for an early ...Bb4, leading to rich and dynamic positions. Key ideas include the tension in the center, where Black aims to challenge White's pawn on d4 while developing pieces harmoniously. Typical pawn structures feature a solid d5 pawn for Black, often leading to a strong knight on c6, while White looks to exploit the c-file and maintain central control, making this opening appealing to players who enjoy strategic maneuvering and counterplay.
